Is it possible to run a T fitting in your fuel supply line, to run propane at first to start it then as you open the Kero valve, start weaning if off propane? Here are pics of my latest build. It's just about finished. I was happy with the blade tip clearance, the turbine being about .008" and the compressor being about .005" If it doesn't run, it's not because of excessive tip clearance.

Hi Jeff
Its not advisable to try and run propane and then fuel through the same manifold , myself and others have tried with mixed results, it'll start and progress to spoolup but as soon as you start feeding in the kero and reducing the propane its very difficult to get the "ratio" right .
Much better to have a dedicated manifold for each , the propane preheat need only be to a segment of the flametube , I generally feed it to the lower evaporators .
Cheers
John
